Melatonin, a hormone regulating circadian rhythms, may also influence DNA methylation patterns. This suggests its potential as an epigenetic regulator and in novel anticancer combination therapies.
Area of Science:
- Endocrinology
- Epigenetics
- Oncology
Background:
- Melatonin, a pineal gland hormone, regulates numerous cellular functions and circadian rhythms.
- Circadian rhythm disruption is linked to genomic instability and epigenetic changes, particularly DNA methylation.
- Melatonin influences DNA methylation, impacting disease development and cancer initiation.
Purpose of the Study:
- To review the potential role of melatonin as an epigenetic regulator.
- To explore melatonin's modulation of DNA methylation via DNA methyltransferases (DNMTs) and ten-eleven translocation (TET) proteins.
- To suggest melatonin's use in combination therapy with epigenetic drugs for cancer treatment.
Main Methods:
- Literature review focusing on melatonin's effects on DNA methylation.
- Analysis of melatonin's impact on the expression of DNMTs and TET proteins.
- Evaluation of evidence linking melatonin, DNA methylation, and disease.
Main Results:
- Melatonin influences DNA methylation patterns.
- Melatonin modulates the expression of key enzymes involved in DNA methylation (DNMTs and TETs).
- Evidence suggests a role for melatonin in epigenetic regulation.
Conclusions:
- Melatonin is an under-investigated epigenetic regulator with the potential to modify DNA methylation.
- Melatonin may be a valuable component in combination therapies with epigenetic drugs for cancer treatment.
- Further research is warranted to explore melatonin's full therapeutic potential in epigenetic modulation and oncology.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
